Yes, and there were long, long lines to view it - and to get into the building! Luckily, I managed a pass to the pavilion and bypassed most of the lines. Saw a moon rock display for a second time at Aichi 2005 (can't remember which pavilion!) I have a photo somewhere of the 1970 US Pav. moon rock. If I find it, I'll try to put it up.

The Expo 70 moon rock came back on the Apollo 11 mission. After as much as a five hour wait in line, many visitors were reported to be disappointed. Apparently because it didn't glow martian green or something.

The U.S. Pavilion also showed off the actual Apollo 8 command module.

Here is an interesting university study on "long-term memory", centering on how accurately Japanese visitors to Expo 70 remember what they saw today. The moon rock is discussed on page 10.http://www.cust.educ.ubc.ca/faculty/fac ... derson.pdf

The authors compare memories of Expo 70 to studies recording memory accuracy for Expo 67, Expo 86 and Expo 88. An interesting topic. It explores the reasons why some memories are more vivid than others, and why they are stronger for some people, but not all people.

For the life of me, I cannot find the moon rock pic (Thanks to Bill for one that is much clearer than mine would be), but I did find a larger view pic of the spacecraft at the pavilion. Enjoy.[attachment=0:uq5ai2jj]expo70usa2.jpg[/attachment:uq5ai2jj]

"In 1970 the LTA-8 descent stage, together with the ascent stage of the unflown LM-2, spent several months at the Expo '70 in Osaka, Japan. Upon return the LTA-8 ascent and descent stages were reunited and put on display at the JSC visitor center where they can still be seen today."

So I guess the LEM in this picture is LTA-8. Another legacy nailed down!

My father, Howard Stingle, who worked for the United States Information Agency, had the privilege of carrying the moon rock from the US to Japan, on his lap on the airplane, anonymously wrapped. He loved getting to do that - he always liked things that made him feel important.
